The Fotocore OSD-M (optical shaping device) is designed for the Fotocore GTM Strobe. It differs from other snoots due to its innovative way of changing the size of the beam of light. Instead of using masks, it has an in-built aperture that can be dialled in to nine different aperture sizes. For a narrow beam of light, a small aperture can be selected and for a wider beam, a larger aperture can be selected by merely turning a knob on the side of the OSD.
The Fotocore OSD-M is very sturdy and made from aluminium. It uses glass lenses to enhance the strength of the focus light and the quality of light emitted from the strobe.
The OSD-M is compatible with Fotocore GTM strobe
The OSD also comes with a groove on its neck, which makes attaching a lanyard possible.
